For hot rolled bars the process layout scheme is mainly divided into continuous rolling and the semi continuous rolling For continuous rolling roughing mill is arranged first then the first medium rolling mill and the second medium rolling mill the last are the finishing mill and the reducing and sizing mill For semi continuous rolling two roll reversing mill continuous rolling mill
Carbide Square End Mills Made of solid carbide these end mills are harder stronger and more wear resistant than high speed steel and cobalt steel for the longest life and best finish on hard material Their extreme hardness means they are brittle so a highly rigid setup such as a CNC machine is necessary to prevent the end mill from
control and slab shape correction These systems allow the rolling of steel slabs into a top quality transfer bar which is then processed on the Steckel Mill The Steckel Mill After exiting the roughing mill the transfer bar travels to the key stone of the SMART system a 110 inch wide four high reversing Steckel mill

The layout of the hot strip mill of voestalpine Stahl is shown in Fig 1 Slabs are heated to rolling temperature in the reheating furnace subsequently descaled and rolled in the roughing stand to the transfer bar thickness and after a second descaling step rolled to the final thickness cooled on the run out table and coiled
Roughing/Finishing End Mills are used for removing large amounts of material quickly but leaving behind a finish that s almost as smooth as a traditional end mill Saves time over a traditional two step hogging finishing process Easily resharpened without altering form for extended tool life A wide range of coatings tool material and number of flutes are available to match most machining
Roughing End Mills also known as ripping cutters or hoggers are designed to remove large amounts of metal quickly and more efficiently than standard end mills Coarse tooth roughing end mills remove large chips for heavy cuts deep slotting and rapid stock removal on low to medium carbon steel and alloy steel prior to a finishing application
